Bill Viola is a contemporary video artist. His art deals largely with the central themes of human consciousness and experience - birth, death, love, emotion and a kind of humanist spirituality. Throughout his career he has drawn meaning and inspiration from his deep interest in mystical traditions, especially Zen Buddhism, Christian mysticism and Islamic Sufism, often evident in the transcendental quality of some of his works. Equally, the subject matter and manner of western medieval and renaissance devotional art have informed his aesthetic.
